Put parentheses around macro argument uses. This avoids pitfalls

Add a new EV_SYN code, SYN_DROPPED, to inform the client when input
events have been dropped from the evdev input buffer due to a
buffer overrun. The client should use this event as a hint to
reset its state or ignore all following events until the next
packet begins.Signed-off-by: Jeff Brown

Many media center remotes have buttons intended for jumping straight to
one type of media browser or another -- commonly, images/photos/pictures,
audio/music, television, and movies. At present, remotes with an images
or photos or pictures button use any number of different keycodes which
sort of maybe fit. I've seen at least KEY_MEDIA, KEY_CAMERA,
KEY_GRAPHICSEDITOR and KEY_PRESENTATION. None of those seem quite right.
In my mind, KEY_MEDIA should be something more like a media center
application launcher (and I'd like to standardize on that for things
like the windows media center button on the mce remotes). KEY_CAMERA is
used in a lot of webcams, and typically means "take a picture now".
KEY_GRAPHICSEDITOR implies an editor, not a browser. KEY_PRESENTATION
might be the closest fit here, if you think "photo slide show", but it
may well be more intended for "run application in full-screen
presentation mode" or to launch something like magicpoint, I dunno.
And thus, I'd like to have a KEY_IMAGES, which matches the HID Usage AL
Image Browser, the meaning of which I think is crystal-clear. I believe
AL Audio Browser is already covered by KEY_AUDIO, and AL Movie Browser
by KEY_VIDEO, so I'm also adding appropriate comments next to those
keys.Signed-off-by: Jarod Wilson

Today, userspace sets up an input device based on the data it emits.
This is not always enough; a tablet and a touchscreen may emit exactly
the same data, for instance, but the former should be set up with a
pointer whereas the latter does not need to. Recently, a new type of
touchpad has emerged where the buttons are under the pad, which
changes logic without changing the emitted data. This patch introduces
a new ioctl, EVIOCGPROP, which enables user access to a set of device
properties useful during setup. The properties are given as a bitmap
in the same fashion as the event types, and are also made available
via sysfs, uevent and /proc/bus/input/devices.Acked-by: Ping Cheng

Touch devices capable of hovering, i.e., fingers detected a
distance from the surface, are not supported by the current
input MT protocol. This patch adds ABS_MT_DISTANCE, which may
be used to indicate the distance between the contact and the
surface.Signed-off-by: Henrik Rydberg
-
The drivers using the type B protocol all report tracking information
the same way. The contact id is semantically equivalent to
ABS_MT_SLOT, and the handling of ABS_MT_TRACKING_ID only complicates
the driver. The situation can be improved upon by providing a common
pointer emulation code, thereby removing the need for the tracking id
in the driver. This patch moves all tracking event handling over to
the input core, simplifying both the existing drivers and the ones
currently in preparation.Acked-by: Ping Cheng

The desire to keep old names for the EVIOCGKEYCODE/EVIOCSKEYCODE while
extending them to support large scancodes was a mistake. While we tried
to keep ABI intact (and we succeeded in doing that, programs compiled
on older kernels will work on newer ones) there is still a problem with
recompiling existing software with newer kernel headers.New kernel headers will supply updated ioctl numbers and kernel will
expect that userspace will use struct input_keymap_entry to set and
retrieve keymap data. But since the names of ioctls are still the same
userspace will happily compile even if not adjusted to make use of the
new structure and will start miraculously fail in the field.To avoid this issue let's revert EVIOCGKEYCODE/EVIOCSKEYCODE definitions
and add EVIOCGKEYCODE_V2/EVIOCSKEYCODE_V2 so that userspace can explicitly
select the style of ioctls it wants to employ.Reviewed-by: Henrik Rydberg

KGDB, much like the resume process, needs to be able to mark all keys that
were pressed at the time we dropped into the debuggers as "released", since
it is unlikely that the keys stay pressed for the entire duration of the
debug session.Also we need to make sure that input_reset_device() and input_dev_suspend()
only attempt to change state of currenlt opened devices since closed devices
may not be ready to accept IO requests.Tested-by: Jason Wessel

Several devices use a high number of bits for scancodes. One important
group is the Remote Controllers. Some new protocols like RC-6 define a
scancode space of 64 bits.The current EVIO[CS]GKEYCODE ioctls allow replace the scancode/keycode
translation tables, but it is limited to up to 32 bits for scancode.Also, if userspace wants to clean the existing table, replacing it by
a new one, it needs to run a loop calling the ioctls over the entire
sparse scancode space.To solve those problems, this patch extends the ioctls to allow drivers
handle scancodes up to 32 bytes long (the length could be extended in
the future should such need arise) and allow userspace to query and set
scancode to keycode mappings not only by scancode but also by index.Compatibility code were also added to handle the old format of
EVIO[CS]GKEYCODE ioctls.Folded fixes by:
- Dan Carpenter: locking fixes for the original implementation
- Jarod Wilson: fix crash when setting keycode and wiring up get/set
handlers in original implementation.
- Dmitry Torokhov: rework to consolidate old and new scancode handling,
provide options to act either by index or scancode.Signed-off-by: Mauro Carvalho Chehab

With the rapidly increasing number of intelligent multi-contact and
multi-user devices, the need to send digested, filtered information
from a set of different sources within the same device is imminent.
This patch adds the concept of slots to the MT protocol. The slots
enumerate a set of identified sources, such that all MT events
can be passed independently and selectively per identified source.The protocol works like this: Instead of sending a SYN_MT_REPORT
event immediately after the contact data, one sends an ABS_MT_SLOT
event immediately before the contact data. The input core will only
emit events for slots with modified MT events. It is assumed that
the same slot is used for the duration of an initiated contact.Acked-by: Ping Cheng

Some devices, in particular MT devices, produce a lot of data. This
may lead to overflowing of the event queues in evdev driver, which
by default are fairly small. Let the drivers hint the average number
of events per packet generated by the device, and use that information

AD7142 and AD7147 are integrated capacitance-to-digital converters
(CDCs) with on-chip environmental calibration for use in systems
requiring a novel user input method. The AD7142 and AD7147 can interface
to external capacitance sensors implementing functions such as buttons,
scrollwheels, sliders, touchpads and so on.The chips don't restrict the specific usage. Depending on the hardware
connection, one special target board can include one or several these
components. The platform_data for the device's "struct device" holds
these information. The data-struct defined in head file descript the
hardware feature of button/scrollwheel/slider/touchpad components on
target boards, which need be filled in the arch/mach-/.As the result, the driver is independent of boards. It gets the
components layout from the platform_data, registers related devices,
fullfills the algorithms and state machines for these components and
report related input events to up level.Signed-off-by: Bryan Wu

short keycodes instead of unsigned char we can release this range back
